At least three persons were killed and 13 others injured after two suicide bomber attacked worshippers during early morning prayers in Gwoza town on Sunday, sources said.
Gwoza is the headquarters of a Borno State local government that shares a similar name. It is one of the reclaimed communities that residents returned after it was sacked by Boko Haram in 2014.
It is also one of the local government areas that still has a large presence of the Boko Haram insurgents at its outskirt communities bordering Cameroon.
Yesterday, the residents were woken by a twin explosion after two suspected suicide bombers detonated their deadly vests near a mosque.
The incident occurred in a neighborhood called Guduf Nagadiyo in Bulabaulin in Gwoza.
The attack, which is the first of its kind after a long time, left many residents horrified.
Security sources said the casualties would have been higher had the suicide bombers made their way into the usually crowded mosque.
The bombers were sighted making an unusual advance toward the mosque, and before worshippers could raise the alarm, the assailants had already gotten to the mosque.
In most northern Muslim communities, early morning congregational prayers are usually attended by males only.
